Question
I have a lemon and an orange tree and for the past year the leaves have gone all bubbly and it seems we might loose these trees if I don't find a cure. Many Thanks

Answer
Hi Clive, you probably have some critters hiding under the leaves making it look that way.  You will need to use an insecticide spray to keep you plant from getting the bugs.  Good clean practices of nothing under your trees but soil, weekly watering, fertilize slow release will also help keep your tree healthy.  kathy
